Even if WebKitPy installs third party libraries by itself and sys.path is setup correctly, the packages in site-package have an priority to be loaded which prevent to import logilab.astng in the thirdpary/autoinstalled directory. The workaround is to install logilab-astng manually globally, but that is not the right solution. 1370445 1 basuke 2017-11-10 12:25:20 -0800 python's cli argument "-S" disables site-package which solve this issue, but need to figure out for the possibility of other new issue. 1370450 2 basuke 2017-11-10 12:32:09 -0800 Actually "-S" doesn't work well because it prevents to load primitive modules. 1370454 3 basuke 2017-11-10 12:36:44 -0800 I confirmed this issue also happens on Mac if logilab-common is installed globally.
